Specification of Letters Patent.

Patented Apr. 28, 1914.

Application filed. July 23, 1913. Serial No. 780,745.

To all whom it may concern:

Be it known that 1, JAMES S. BURNS, a citizen of the United States, residing at Excel, in the county of Monroe and State of Alabama, have invented new and useful Improvements in Door-Holders, of which the following is a specification.

This invention relates to door holders for application to the wall adjacent the hinging jamb of the door frame for coaction with the bolt of the door lock to automatically engage and hold the door in open position, while stopping the opening movement of the door and preventing the door knob from coming in contact with and injuring the wall.

The primary object of the invention is to provide a holder of the character described which is simple, reliable, eflicient and inexpensive of construction, adapted for application to walls having surfaces of different materials, capable of yielding to a desirable degree under the contact of the door bolt there with to avoid liability of injury to the door or stop, and which at the same time admits of the ready release of the door for closing movement. I

A further object of the invention is to provide a holder of the character described composed of spring metal and of sectlons adjustably connected so that the distance be tween the wall and stop and lock surfaces of the device may be varied as occasion demands.

The invention consists of the features of construction, combination and arrangement of parts herein fully described and claimed, reference being had to the accompanying drawing in which:

Figure 1 is a horizontal section through a wall and door, showing the door in open position and in engagement with my improved door holder. Fig. 2 is a side elevation of the door holder detached. Fig. 3 is a top plan view thereof. Fig. 4 is a longitudinal section on the line 4- -4 of Fig. 2. Fig. 5 is a vertical transverse section on the line 5-5 of Fig. 2.

In carrying my invention into practice I provide the relatively adjustable sections 1 and 2. The attaching section 1 is com osed of a bracket plate3 having openings 4 t 'ierein for passage of screws or other suitable fastening devices, and an arm 5 extending forwardly from one of the side edges of said bracket piece. The arm 5 is provided with a longitudinal guide slot 6, and at its point of connection with the plate 3 is curved, as at 7, to allow the arm 5 to have a desired degree of lateral spring action or resiliency.

The section 2 constitutes a stop and locking section, and is composed of a plate 8, substantially coextensive in dimensions with the arm 5 and provided with an opening 9 for the passage of a bolt 10, which also passes through the slot 6 in the arm 5 and is provided with a binding nut 11, whereby the two sections of the device are adjustably connected. The forward or outer end of the plate 8 is bent to provide a substantially V-shaped, laterally offset striker-head 12, having relatively inclined or beveled surfaces 13 and 14, the inner or rear beveled surface 14 being arranged in juxtaposition to a stop plate 15. projecting laterally from the plate 8 and forming therewith a receiv ing space or recess 16, the beveled or inclined faces 13 and 14 of the convex surface of the striker-head 12 converging at a point substantially in line with the outer edge of the stop plate 15, as clearly shown in Fig. 2. For the purpose of guiding the section 2 on the arm 5 of the section 1, and preventing pivotal motion thereof, one of the aforesaid parts is provided with hook shaped guide lugs or projections 17 engaging the other and insuring movement of the plate 8 in a determined straight path, while holding the section 2 rigid against pivotal motion on the fastening bolt.

The bracket plate 3 is fastened to the wall 18 of a room adjacent to the hinge j amb 19 of the frame, so that the striker-head 12 and stop plate 15 will lie in the path of the looking bolt 20 on the swinging door 21. When the door is swung open the straight face of the bolt 20 comes in contact with the inclined surface 14 of the striker-head and rides up on said surface, receding to a certain extent within the lock casing until it passes the point of greatest projection of the convex face of the striker head, at the angle of the surfaces 13 and 14, whereupon said bolt slides over into the receiving space 16, as a result of which the door will be locked in closed position. 7, When the bolt 20 passes into the recess or receiving space 16 and contacts with the stop plate 15, the latter stops the opening movement of the door, and it will be understood that as the device is made of spring metal and is sufficiently flexible at the point 7 the adjustable section 2 and arm 5 will yield on contact of the locking bolt with the strikerhead to avoid liability of injury to the bolt or stop. When it is desired to close the door a slight pull upon the door in its closing direction will cause the beveled surface of the locking bolt 20 to ride over the surface 14 until the highest point of the convex face striker-head is reached, the bolt receding on such motion into its casing, whereby the bolt will be released, allowing the door to be closed.

It will be observed that the striker-head 12 serves in eifect as a cam, which engages the locking bolt and causes its recession into its casing on the opening movement of the door to adapt it to snap into the keeper recess 16, so that the momentum of the door will be decreased when the bolt comes in contact with the stop 15, whereby, in connection with the yielding or spring action afforded by the surface 7 and the spring material of which the stop and lock is made, the shock of contact is reduced, thus avoiding liability of injury either to the latch bolt or holder. The stop 15 is so arranged that when the door is fully swung open and engaged with the holder suflicient space will be left between the free edge of the door and the wall to receive the adjacent door knob, and so as to prevent the knob from coming in contact with and injuring the wall.

By means of the adjustable connection between the sections 1 and 2, it is apparent that the device may be varied in length to regulate thedistance between the attaching Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

plate and the striker-head and stop plate having av resilient arm extending for ardly therefrom, a stop member slidably adjustable on said arm, fastening means for holding the stop member in adjusted position, a laterally projecting cam-shaped strikerhead carried by the stop member, and a stop plate carried by the stop member in rear of said striker-head and arranged in spaced relation thereto to provide an intervening bolt receiving recess.

2. A door holder comprising an attaching member composed of a bracket plate having a resilient arm extending forwardly therefrom, said arm being provided with a. longitudinal slot, a stop member having guiding projections engaging said arm to hold said stop member from other than a sliding movement on the arm, a bolt passing through said members and. through the aforesaid slot for adjustably connecting and securing said members in adjusted position, a laterally projecting cam shaped strikerhead carried by the stop member, and a stop plate carried by the stop member in rear of said striker head and arranged in spaced relation thereto to provide an intervening boltrecoiving recess.

In testimony whereof I ailix my signature in presence of two witnesses.
